Letters Patent No. 93,327, dated August 3, 1869.

IMPROVEMENT IN SEED-DRILLS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom @'tfmay conce/rn:

Be it known that we, SOLOMON MICKLEY, ot' Dover township, and SAMUELLEATHERY, of Warringfon township,in the county of York, and in the Stateof Pennsylvania, have invented certain new and useful Improvements in-Seed-Drills; and do hereby declare that vthe following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, making a partof this specication.

The nature of our invention consists in the con struction of aseed-drill, and in the arrangement of the devices hereafter set forthand explained.

Figure 1 is.- a front elevation of our drill, part of the frame-beingremoved.

Figure 2 is a section view of the same.

Figure 3 is a section of the drum.

Letter A represents the axle, upon which the frame rests, and'which issupported by"the drivingwheels B.

Near thecentre of this axle there is placed the spur-wheel C, providedwith a short toothed sleeve on one side, and which turns independentlyvof the axle.

By the side of this wheel is placed the collar D, which slides back and'forth on the axle, lso as to throw the spur in and out of gear.

Upon one end of this collar there are notches out, 'so as to engage withthose on the side of the wheel, and it has a groove cut iuits surface,in which the lower end of the lever'G catches, so as to move it back andforth.. I

Upon the top of the two beams I, which form a part of the frame, isplaced a shaft, to which are se cured the wheel I-I, near its centre,and a drum, K, at each end.

The upper portions of these drums are covered by the seed-boxes L,*inwhich are placed the brushes N, so as toY sweepthe grains from the topof the drums, and prevent them from gettingl between the side of theboxesand the drums.

In the sulface of the drums there is a number of openings made, in whichthere is sunk a screw, which can be raised or lowered, so as to regulatethe number of grains to a hill.

As the grains fall from the drums, they are caught in the spouts M,andconveyed by the boots, secured chains V, for the purpose of raisingand lowering them.

Near the centre of this shaft there is placed a spiral gear,X, whichcatches in a slot in the top of the lever G, so that whenthe baristurnedbackward, by means ofthe hand-lever NV, the plows are raised, and theWheel C thrown out ot' gear at the same time. .y

Itising upward from the side of the frame is the rod Y, bent at its top,so as to catch the. hand-lever, and keep the plows raised above theground.`

Having thus described our invention,

vWhat we claiur as our invention, and desire to secure by LettersPatent, is-

1. The rshaft T, provided with the spiral gear X, and chains V, andlever W, when used to raise the plows, and throw the wheel C out of gearby the same motion, substantially as set forth anddescribed.

2.Tl1e slotted lever G, operated by the spiral gear X, in combinationwith the movable collar D, wheels O andv H, drums K, brushes N, 'andseed-boxes L,

when used substantially as specified.

3. The axle A, wheels O and H, movable collar D, lever G, drums K,brushes N, seed-boxes L, shaft T,

vprovidedwith spiral gear X, hand-lever W,.chains N,
